    56We actually brought this speaker to the MFT2013, but it was not clear to the visitors how this speaker was super directional. Super directional ultrasonic speaker sends the sound only straight out, meaning you can hear the audio only if you are right in front of the speaker. To feel this effect clearly, I made the remote controlled base so that the speaker can face different directions.[[BR]
